This video shows footage of an incredibly rare prehistoric shark known as a Frilled Shark swimming around an enclosure at the Awashima Marine Park in Japan.

These sharks usually live at a depth of 2,000 feet so to get footage such as this is pretty amazing. A fisherman spotted the shark in shallow water and contacted officials at the park, who came and transported the shark to the park.

Unfortunately the shark wasn’t long for this world, which is probably why it was near the surface in the first place, and it died a few hours after this footage was filmed.

These sharks are known as living fossils because they closely resemble animals which are now extinct, and they are very strange looking compared to what have come to expect from modern day sharks.

It’s definitely a weird creature, and probably only the tip of the iceberg as to the oddities which live at deep sea levels in our oceans. I think I’ll stick to owning goldfish and Koi carp!
